Saving the GUI Session

After you process the data, as described in Plotting and Processing Data, you can delete any data sets in the window that you do not need for estimation and validation, and save your session. You can open this session later and use it as a starting point for model estimation and validation without repeating these preparatory steps.

You must have already processed the data into the System Identification Tool, as described in Plotting and Processing Data.

To delete specific data sets from a session and save the session:

1. In the System Identification Tool GUI, drag and drop the data data set into the Trash.

2. Drag and drop the datad data set into the Trash.

   Note   Moving items to the Trash does not delete them. To permanently delete items, select Options > Empty trash in the System Identification Tool GUI.

   The following figure shows the System Identification Tool GUI after moving the items to the Trash.

   

3. Drag and drop the estimate and validate data sets to fill the empty rectangles, as shown in the following figure.

   

4. Select File > Save session as to open the Save Session dialog box, and browse to the folder where you want to save the session file.

5. In the File name field, type the name of the session dryer2_prep_data, and click Save. The resulting file has a .sid extension.

Tip   You can open a saved session when starting the System Identification Tool. For example, you can type the following command in the MATLAB Command Window: ident('dryer2_prep_data')

For more information about managing sessions, see the topics on working with the System Identification Tool GUI in the System Identification Toolbox User's Guide.
